Being on vacation is no excuse to drop the workout routine. Just ask Nicole Richie who recently headed to the beach for some sun, sand and paddleboarding. Richie, 31, is the picture of health these days, thanks to a healthy diet and Tracy Anderson's intense cardio-dance workouts, plus activities like paddleboarding that combine fun and fitness. Standing on the board atop waveless water like lakes, rivers and bays is a balancing act that strengthens the muscles of the legs, buttocks, back, shoulders and arms. Good for people of any age, this activity also soothes the soul. Is there anything better than being out on the ocean, taking in some sunlight and some peace and quiet? We didn't think so.
